So right now my Sin is lvl 32 with 2 in both Venom and Shadow Master, 37% chance to block with my claws, doing (with Venom) about 130-350 and 115-190 damage.. somewhere around there, dont have exact numbers now. Found a nice rare claw while gambling tho - +35-78 Fire Damage and +5-17 or so Cold Damage.. got a bunch of Poison GCs in my pack (no SCs yet sadly), and Im doing pretty well in Norm so far. Just killed Meph on /p 8 in Single Player in about a minute.
My question is, how well does Venom stick up in NM and Hell? I'm gonna see the Sin thru till Baal at least, but am I SOL when it comes to Act 3 NM and onward?
Should I go back to my Necro? :P
Tips? Tricks? Im maxing Venom then Shadow Master then the attack spd buff, then the passive damage skill (sorry cant remember names lol im gettin tired)
Venom doesn't work very well with poison charms. All charms are capped to the duration of venom meaning that, for example, a charm with 100 damage over 5 seconds, would only give you (100/5)*0.4 = 8 extra poison damage. I wouldn't want to say it is not a hell viable skill (crazier things have been done, certainly in SP), but you do want to have something along side of it to do damage. There are plenty of poison immunes in Hell, and the undead generally have high poison resistance.
Now I assume you want to max BoS and Claw Mastery from your post. Don't do this. BoS never requires more than few points and neither does Claw Mastery. Claw Mastery has a big brother called Dragon Claw, however, you only want to focus on physical damage if you have good physical damage claws. Perhaps an elemental charge-up (FoF or CoT) with PS for the synergy might suit you better. All you need is some +skills, which can be obtained rather easily.
If you like necros a point into Death Sentry for the corpse explosion, might be nice too.
